Sul­phur, the Earth’s coolant A nat­u­ral cli­mate changer

Asian Geographic - - Front Page - BY CARL- BERND KAEHLIG

Vol­cano erup­tions are a nat­u­ral cause of cli­mate change. Par­ti­cles can reach the strato­sphere as far as 20 kilo­me­tres, re­leas­ing large vol­umes of sul­phur diox­ide (SO2) and car­bon diox­ide (CO2). It is here in In­done­sia’s craters, from the Gu­nung Ijen in West Java to Gu­nung Ke­limutu in Flores and Gu­nung Pa­pan­dayan that we see na­ture’s way of bring­ing down the tem­per­a­ture.
